Approach 1: Delta Air Lines Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model estimates what a business could be worth today by projecting the cash it might generate in the future and discounting those cash flows back to the present.

For Delta Air Lines, the model used is a 2 Stage Free Cash Flow to Equity approach based on cash flow projections. The latest twelve month free cash flow is about $3.09b. Analyst inputs and extrapolations point to free cash flow of $2.30b in 2026, rising to a projected $7.62b by 2035, all in $. Simply Wall St uses analyst estimates where available and then extrapolates further years to build a ten year cash flow path.

When these projected cash flows are discounted back and combined with a terminal value, the model suggests an intrinsic value of about $148.65 per share, compared with the current share price around $67.82. That implies an intrinsic discount of roughly 54.4%, so on this DCF view the shares screen as undervalued.

Result: UNDERVALUED

Approach 2: Delta Air Lines Price vs Earnings

For profitable companies, the P/E ratio is a useful quick check because it links what you pay per share directly to the earnings the business is currently generating. Investors typically expect higher P/E ratios when they see stronger growth potential or lower perceived risk, and lower P/E ratios when growth expectations are more modest or risks are higher.

Delta Air Lines currently trades on a P/E of about 9.9x. This sits above the Airlines industry average P/E of around 8.7x, but well below a broader peer group average of roughly 32.0x. To refine this simple comparison, Simply Wall St uses a “Fair Ratio” which estimates what P/E might be reasonable for Delta given factors such as its earnings growth profile, industry, profit margins, market value and company specific risks.

This Fair Ratio for Delta is 16.7x, which is higher than the current 9.9x. Because the Fair Ratio adjusts for growth, risk, profitability, industry and size, it can be more informative than a basic comparison with industry or peers. On this basis, Delta’s current P/E suggests the shares are trading below the level implied by these fundamentals.

Result: UNDERVALUED

Upgrade Your Decision Making: Choose your Delta Air Lines Narrative

Earlier sections showed how DCF and P/E models can flag Delta Air Lines as potentially undervalued, but Narratives go further by letting you spell out the story you believe about Delta, link that story to explicit forecasts for revenue, earnings and margins, and then see the fair value that drops out of those assumptions on Simply Wall St's Community page, where millions of investors share their views.

In practice, a Narrative is your own version of the Delta story translated into numbers. It helps you compare the fair value you arrive at with the current share price so you can decide whether the stock looks expensive or cheap against your expectations.

Narratives on Simply Wall St update when new information comes in. This means that if fresh earnings or news affects your view on travel demand, tariffs, costs or Delta's premium strategy, your forecast and fair value can move with it rather than staying static.

For Delta right now, one investor might plug in assumptions similar to the more cautious view with a fair value around US$59.00. Another might lean closer to the optimistic case around US$80.04, and Narratives make these different perspectives visible and comparable in one place.

For Delta Air Lines, however, we will make it really easy for you with previews of two leading Delta Air Lines Narratives:

🐂 Delta Air Lines Bull Case

Fair value: US$79.89

Current price vs this fair value: about 15.1% below that narrative fair value

Revenue growth assumption: 4.79% a year

• Focus on premium cabins, loyalty revenue and international routes supports the earnings profile that analysts are using in their models.
• Flat capacity growth and aircraft retirements are expected to help manage costs and protect net margins while still supporting free cash flow.
• Analyst targets cluster around US$80, but views differ, so the narrative depends on your confidence in revenue, margins and a future P/E of about 12.2x by 2029.

🐻 Delta Air Lines Bear Case

Fair value: US$63.21

Current price vs this fair value: about 7.3% above that narrative fair value

Revenue growth assumption: 3.5% a year

• This narrative highlights very strong unit economics today, but questions how much of that strength is already reflected in the share price.
• Concerns focus on a stretched balance sheet, thin industry margins and sensitivity to external shocks such as tariffs or weaker economic conditions.
• This view assumes more modest revenue growth and a future P/E of around 10x, which pulls fair value closer to the low US$60s.
